我在将 ASP.Net 导出为 PDF 时遇到了困难。下面是我的代码。请帮忙。

Response.Clear();    
Response.Buffer = true;    
Response.Charset = Encoding.UTF8.HeaderName;    
Response.ContentEncoding = Encoding.UTF8;

Response.Write(string.Format("<meta http-equiv=Content-Type content=text/html;charset={0}>", Encoding.UTF8.HeaderName));

Response.ContentType = "application/pdf";    
Response.Headers.Add("Content-disposition", "attachment; filename=pdffilename.pdf");

StringBuilder sb = new StringBuilder();    
sb.Append("MIME-Version: 1.0\r\n");    
sb.Append("X-Document-Type: Worksheet\r\n");    
sb.Append("Content-Type: multipart/related; boundary=\"----=mtrSystem\"\r\n\r\n\r\n");    
sb.Append("------=mtrSystem\r\n");    
sb.Append("Content-Type: text/html; charset=\"utf-8\"\r\n");    
sb.Append("<html xmlns:o=\"urn:schemas-microsoft-com:office:office\"\r\n");    
sb.Append("xmlns:x=\"urn:schemas-microsoft-com:office:pdf\">\r\n\r\n\r\n");     
sb.Append("------=mtrSystem\r\n");    
sb.Append("Content-ID: baiduimg\r\n");    
sb.Append("Content-Transfer-Encoding: base64\r\n");    
sb.Append("Content-Type: image/png\r\n\r\n");

我可以使用这种方式将 ASP.Net 页面导出为 PDF 吗？

Html-to-pdf.net 允许将 html 转换为 pdf。要从 asp.net 页面获取 html，请使用以下代码：

StringWriter sw = new StringWriter();
Server.Execute("PageToConvert.aspx", sw);
string htmlCodeToConvert = sw.GetStringBuilder().ToString();

然后将 html 传递到 pdf 生成器：

public byte[] GetPdfBytesFromHtmlString (string htmlString)

然后您可以将字节保存到响应中以发送到客户端，或作为本地文件保存在服务器上。

编辑：

需要记住的一点是，html-to-pdf 确实需要花钱，但对于我的上一个项目来说，这是一笔合理的开支。您可以使用试用版来确定您需要什么。

Html-to-pdf.net allows for converting html to pdf. TO get the html from an asp.net page, use the following code:

StringWriter sw = new StringWriter();
Server.Execute("PageToConvert.aspx", sw);
string htmlCodeToConvert = sw.GetStringBuilder().ToString();

Then pass the html to the pdf generator:

public byte[] GetPdfBytesFromHtmlString (string htmlString)

You can then save the bytes to the response to send to client, or save on the server as a local file.

EDIT:

Something to keep in mind, html-to-pdf does cost money, but for my last project it was a justified expense. You can use the trial version to figure out what you needd.
